Orion Nebula - the place where stars are born.
Orion OB1 association consists of the following subgroups:[1][2]
Orion OB1a - the group of stars northwest of the Orion Belt stars with an average age of about 12 million years. Within this grouping is another subgroup known as the 25 Orionis group. They are located near the star of Bellatrix.
Orion OB1b - the three bright stars ζ Ori (Alnitak), ε Ori (Alnilam), and δ Ori (Mintaka) which make up the asterism known as "Orion's Belt", and minor stars. This group has an average age of approximately 8 million years and is further subdivided into three subgroups.
Orion OB1c - the stars in Orion's Sword that are created by 42 Orionis, θ Orionis, and ι Orionis. These stars are about 3-6 million years old.
Orion OB1d - the stars of the Orion Nebula and M43 (the youngest stars).
OB1d should be the most interesting one.
